what mathematical equation for speed. The wave equation is a partial differential equation that may constrain some scalar function u u x 1 x 2 x n. It travels 30 miles in the first hour 45 miles in the second hour and 75 miles in the third hour.
The rate is the speed at which an object or person travels. The formula for speed is s dt where s equals the speed d is the distance covered and t is the time it took to cover the distance. It can also be expressed as the time derivative of the distance traveled.
Mathematically it can be written as v st or v dsdt where speed is denoted by v distance is denoted by s and time is denoted by t.
Speed in the first hour 30 miles hour. Velocity distance time. It can also be expressed as the time derivative of the distance traveled. So 1 ms is equal to 36 kmh.
